The Antichrist will have four close partners.  First, the False Prophet throws his support behind this Man of Sin.  Second, the final 10 EU nations all agree in Revelation 17 to give him their kingdom.  The Beast or Antichrist and these 10 horns or kings make war with Jesus Christ, as they will be defeated by Him.  Third, the Dragon or Satan gives supernatural power to this man, causing him to succeed during this 42 month period preceding the coming of Jesus Christ.  And, fourth, he carries the Babylonian woman in Revelation 17, who is spoken about as a king, and the King of Babylon in Isaiah 14, who has destroyed his land in verse 20.  This land is called the Glory of Kingdoms in Isaiah 13:19.  This episode will be helpful in your understanding of these future events.
